That is a very attractive color and you likely appreciate the changing colors and radiance every time you use this. Same here, nice to use a soft lead just for the change. Also useful for sketching as I can create more effects with lead and also shading simply by smearing my finger of the lead image.
For some odd reason I never did get used to roller balls, seems the feel of the lack of tactile resistance on the paper. Thanks for showing this beautiful pencil.
